int d_button_proc(int msg, DIALOG *d, int c);
DESCRIPTIONA button object (the dp field points to the text string). This object can be selected by clicking on it with the mouse or by pressing its keyboard shortcut. If the D_EXIT flag is set, selecting it will close the dialog, otherwise it will toggle on and off. Like d_text_proc(), ampersands can be used to display the keyboard shortcut of the button.
